_______________❀Product Information❀______________
1. High Performance: TPA3255 chip is a high performance amplifier chip, which has class D efficiency and can bring real high end sound quality.
2. Integration Feedback, Error Correction: HIFI digital power amplifier board features advanced integrated feedback design and proprietary high speed gate driver error correction function (PurePath™ Ultra HD).
3. Low Distortion Sound: HIFI digital power amplifier board enables the device to maintain ultra low distortion in the whole sound frequency band, while exhibiting sound quality.
4. Loading Capacity: digital power amplifier board works in AD mode, and can drive up to two 315W 4R loads and two 150W (uncut power) 8R loads when THD is 1.5%.
5. Input Interface, Connection: Digital power amplifier board has a 2 VRMS analog input interface, which supports seamless connection with high performance DAC (such as PCM5242 of TI).
6. High Efficiency and Low Loss: Amplifier board has two advantages: high power efficiency and ultra low idle loss (less than 2.5W). It is realized by 85mR MOSFET and optimized gate driver scheme.
